GENERAL GUIDELINES FOR THE INSTALLATION OF STEEL WINDOWS SEALING THE EXTERIOR PERIMETER GAP Seal the exterior gap between the window and the structural opening with a sealant that is compatible with the window and opening material, the gap size and configuration, the weather exposure, and the expected movement of the window. Follow the recommended installation instructions of the sealant manufacturer. Gaps of 1/8" can usually be filled with sealant only, however gaps over 3/16 usually require a backing material such as backer rod to support the perimeter seal. The depth of the sealant in the joint gap should be Ñ" for non-porous materials, and 3/8" if porous materials are present in the opening. © The Steel Window Institute (2006) Contents are the property of the Steel Window Institute, its members or others who have licensed the information.
